When trying to run a Task on many systems and some of those machines will fail, and when those jobs fail the only status they get is "Replicated" as seen below:
ITMS 8.x
System is Unknown, or Agent Status is Not Tracked
Run the following query to find machines with asset status other than "active":
SELECT *
FROM vRM_Computer AS rmc
LEFT OUTER JOIN ResourceAssociation AS resAssoc
ON rmc.Guid = resAssoc.ParentResourceGuid
AND resAssoc.ResourceAssociationTypeGuid = '3028166F-C0D6-41D8-9CB7-F64852E0FD01'
WHERE (rmc.Deleted = 0)
AND (resAssoc.ChildResourceGuid <> '0A0203A5-D2B6-49f1-A53B-5EC31A89437C') -- 'GUID for Active status
If the machine used for testing is in the results then run this query:
select * from vComputerResource where Guid = 'GUIDgoesHere'
If the test machine is not there then this means that the Task Server doesn't see it as an "active" machine that can be assigned tasks.
